cfnb

Auto-selects the fastest Cloudflare IPs and updates your DNS to use them.

Servicefreeglobal

cfnb is a self-hosted tool that tests candidate Cloudflare edge IPs for latency, jitter, and bandwidth, then automatically updates a user's DNS records to use the fastest ones. It's built for self-hosters and site operators on Cloudflare who want better performance without manually testing IPs.
